Is this the device from the ethertap module? It is better to use the tun module
and /dev/net/tun. If I remember correctly, the ethertap module used a fixed MAC
address, this can cause conflicts if you run tinc in switch mode.

Your configuration files look fine otherwise. If switching to the tun module
does not help, could you use tcpdump to find out which packet (in particular,
with which source and destination MAC address) is causing the "looping back to
myself" message, and run "tincd -n <netname> -kUSR2" to let tinc dump the known
MAC addresses at that moment to the syslog?
